11:12 And it came to pass that he built a tower near the temple; yea, a very high tower, even so high that he could stand upon the top thereof and overlook the land of Shilom, and also the land of Shemlon, which was possessed by the Lamanites; and he could even look over all the land round about.

 11:13 And it came to pass that he caused many buildings to be built in the land Shilom; and he caused a great tower to be built on the hill north of the land Shilom, which had been a resort for the children of Nephi at the time they fled out of the land; and thus he did do with the riches which he obtained by the taxation of his people.
